This review will be slightly different from our usual, as we have received two Patriot Viper 4 Blackout 16GB memory kits. One is rated at DDR4-4400 CL18 with a capacity of 16GB RAM which is optimal for gaming, but many users already thinking about having higher capacity. So today, we will compare these two setups, and show you how they run on the AMD Ryzen platform. For tests will be used Ryzen 5 Pro 4650G, which isn’t limited so much by the infinity fabric frequency as the 3000 or 5000 series.
